Pendred will play Michael Cleary, a real-life character from Irish folklore in the horror anthology series. A cooper who makes barrels for a local creamery, Michael is married to the younger Bridget. When Bridget starts making more money than he does, and starts questioning his decisions, Michael is convinced that his loving wife has been replaced by a changeling — and he will do anything to prove himself right.

Since retiring from professional mixed martial arts last year, former UFC welterweight Pendred has appeared in TV series Ray Donovan and Into the Badlands, and he’ll next be seen in a supporting role in the upcoming Lionsgate biopic My Name Is Lenny. Cathal is repped by Gersh and Paradigm Sports Management.
